Problem with Mac Mini and SleepWatcher

I want to run script before sleeping and another one after wakeup.
I tried to use Sleepwatcher, but it does not works.

I install Sleepwatcher like it tell me ReadMe file, write a simple scripts (unmount disk before sleeping and one more to iTunes Play after wakeup). Put this scripts in my Home directory. But it does not runs via sleepwatcher. I mean nothing hapens before sleeping and after wakeup. If I run this scripts by myself - it works well.

Can someone tell me step by step what should I do?
And I used a hibernate mode, not just sleeping.

May be there is another way to run this scripts? For example via launchd and StartService() StopService()? I just heared about this but not sure
